bowenoid actinic keratosis
Friday 12 October 2012
It is usually a focal change, indistinguishable from Bowen’s disease.
Overlying parakeratosis is often present.
Some authors rarely use the term these days, and only as a ‘fence-sitting’ diagnosis on 2 mm biopsies (or smaller). The pagetoid variant of actinic keratosis is closely related.
